TECHNICAL FIELD

The present disclosure relates to the technical field of boxes and bags, in particular to a novel refrigeration and/or insulation bag.

BACKGROUND

As people's living condition improves, there are more and more activities that people can participate in for enjoyment when they are not working, such as going for an outing, traveling, hiking, caving and so on. During the outdoor activities, backpack is an indispensable tool for carrying more necessities such as water, clothing and so on.

Spring and summer are the peak seasons for outings, and quite a few tourists would choose to go mountaineering, the number of tourists who choose to go mountaineering is on the rise every year. However, what people want after a long period of activities in hot weather is usually a nice cold drink which cannot be provided by a conventional backpack.

In order to solve the problem in providing iced drink outdoors in summer, cooler bags for keeping low temperature have emerged on the market. For example, the Chinese patent No. CN213849209U discloses a cooler bag for holding ice packs, comprising a backpack main body, the backpack main body includes carrying straps and a cover that is detachably connected with the backpack main body by a zipper, and the inner walls of the backpack main body are all fixedly provided with accommodating components, the accommodating components are provided with ice holders for accommodating the ice packs, the accommodating components are provided with switching mechanisms for sealing the ice holders, and the accommodating components are provided with openings for releasing cold air.

For this kind of cooler bags, ice packs are placed in the ice holders in use, and items in the cooler bag are cooled by the cold air released by the ice packs. However, since ice packs need to be placed in the cooler bag before use to create a low temperature environment, on the one hand, the time for keeping cold by the ice packs is limited, on the other hand, the ice packs can only create a roughly low temperature, and the temperature cannot be precisely controlled. Further, the ice packs need to be replaced frequently, which causes high cost and operation troubles. In some conditions, the user would like to keep the items, such as foods and so on, warm in the bag. A common design is to configure an insulation layer to slow down the heat dissipation. However, such design can only achieve limited heat preservation interval and poor effects.

According to the present embodiment, a novel refrigeration bag is provided, the structure of the refrigeration bag is shown in FIG. 1 to FIG. 2. The refrigeration bag, as a whole, includes a bag body 1 having a box shape and located at the lower part. The bag body 1 is externally fixed with straps, and the interior of the bag body 1 forms a cavity, and a top end of the bag body 1 is provided with an opening. The cavity is used for holding items such as drinks and food etc. A top cover 2 is rotatably connected to the top part of the bag body 1 at the position of the opening, and the front part of the top cover 2 is detachably connected to the bag body 1 by a snap-fit component 5.

As shown in FIG. 1, FIG. 3 and FIG. 4, an interior of the top cover 2 forms an accommodating cavity 21, and a refrigeration assembly 3 is embedded in the accommodating cavity 21. The refrigeration assembly 3 includes a temperature-uniforming plate 33 fixed on a bottom part of the top cover 2 for sealing the accommodating cavity 21. Three semiconductor chilling plates 31 arranged in parallel are attached on the temperature-uniforming plate 33. A fixing plate 34 is arranged above the temperature-uniforming plate 33, and the fixing plate 34 is provided with three accommodating recesses 35 for accommodating and fixing the semiconductor chilling plates 31 and conducting wires 42.

A heat dissipation finned plate 36 is arranged above the fixing plate 34, and heat dissipation fans 32 are connected to the top of the heat dissipation finned plate 36. The cold sides of the semiconductor chilling plates 31 are attached to the temperature-uniforming plate 33, while the heat sides thereof are attached to the heat dissipation finned plate 36. The heat dissipation finned plate 36 include a base plate 361 located at the bottom, and a plurality of fins 362 parallel to each other are vertically formed on the base plate 361. The heat dissipation fans 32 are attached to the top of the fins 362.

When the power supply component 4 is a power adapter, it can directly supply power to the refrigeration assembly 3 by a vehicle-mounted power or by plugging in other power supplies. When the power supply component 4 is a storage battery 41, the storage battery 41 and the refrigeration assembly 3 are electrically connected through conducting wires 42. Further, side surfaces of the top cover 2 are provided with several heat dissipation holes 26.

A power supply component 4 is provided on a first side of the top cover 2, and a charging interface 23 is provided on a second side of the top cover 2, which are respectively used for starting the entire refrigeration assembly 3 and charging or discharging of the storage battery 41.

The plates made of the above materials can all achieve a good temperature-uniforming and refrigeration effect, and the aluminum plate is the most cost-effective material. The charging interface 23 may be a Type-C interface, a USB interface, an HDMI interface, or a Lightning interface. Preferably, the charging interface 23 is a Type-C interface. Since the Type-C interface can directly perform charging and discharging operations, the user can, in turn, use the storage battery 41 to charge electronic devices such as mobile phones or tablets and so on, thereby further improving the degree of convenience.

In addition, the sidewall and bottom surface of the cavity inside the bag body 1 are both provided with an insulation layer.

After the refrigeration assembly 3 starts to work, the effective cold-reserving time in the bag body 1 can be extended. As long as the storage battery can provide sufficient power supply, the time of maintaining low temperature can be extended for multiple times, so as to offer good adaptability to users who need long-time low-temperature storage.

In this application, the available materials for the insulation cotton layer 112 include PU foamed cotton, PE foamed cotton, NBR thermal insulation cotton, or EVA thermal insulation cotton. The insulation cotton layer 112 has good temperature-reserving and insulation effect, so the insulation cotton layer 112 is the most important part for keeping the low temperature in the bag body 1.

As shown in FIG. 6, an inner layer 113 made of TPU material, PVC material, PEVA material or other thermal insulation cotton materials is further provided inside the insulation cotton layer 112. On the one hand, the inner layer 113 can fix the insulation cotton inside the bag body 1. On the other hand, the inner layer 113 can also achieve a good moisture-proof effect, so as to keep the inner cavity of the bag body 1 dry and make the bag more suitable for storing food and drinks.

The overall weight of the bag body made of the above materials is low, so the refrigeration bag is light, convenient, and easy to carry. At the same time, the bag has good heat insulation effect and ultra-long cold-reserving time, plus the refrigeration assembly powered by electricity, the bag can achieve refrigeration effect with unlimited time. In combination with storage battery, vehicle-mounted power supply or other mobile power supplies, the cold-reserving time can be extended indefinitely, which is convenient for users who need ultra-long cold-reserving time.
